HAY-CARRIER.

SPECIFICATION forming part of Letters Patent No. 646,261, dated March 27', 1900.

Application iled November 1, 1899. Serial No. 735.460. (No model.)

To all whom t may concern: Be it known that l, JOHN H. BURKHOLDER, a citizen of the United States, residing at Ashland, in the county of Ashland and State of Ohio, have invented new and useful Improvements in Hay-Carriers, of which the following is a specification.

My invention relates to improvements in hay-carriers, and has for its object the providing of means by which the carrier sustains a fixed relation to the track while the load is being elevated and may then be disengaged therefrom and the brake-shoe dropped upon the hoisting-rope to hold thefrope and load against reverse movement-while it is being moved on the track to the place of deposit.

In the accompanying drawings similar letters of reference refer to similar parts.

Figure 1 is a side View of a hay-carrier, illustrating my invention. Fig. 2 is a longitudinal section showing the carrier locked to the stop-block. Fig. 3 is a perspective view of the swinging yokeor latch. Fig. 4 is a vertical section showing the relation of the parts when the brake-shoe is vengaged with the rope. Fig. 5 is a side view of the lower portion of the frame and pulleys when the double blocks are employed for the use of the hay-sling. A represents the track. B represents the upper part of the carrierframe, the lower portions being circular in' form and having provided thereon a rib b, which forms the inner member of the swivel. On the upper portion of the frame there are mounted the carrier-wheels bf, which may be of any desired form adapted to the track to be used.

O is the lower portion of the frame, cast in two parts, the upper portion thereof being semicircular in form and provided With the swivel-ring c, which engages the rib b upon the upper portion of the frame B, the two parts of the frame C being bolted together by bolts c land c2. The lower portion of the frame C has cast integral therewith the sheave c3, which forms a frame or casing for the large pulley c4. The lateral projecting frame o5 is formed upon one side of the lower portion of the frame O and through which the hoistingrope passes and forms the lower portion of the brake or grip, by means of which the load leVer cT there is journaled the clevis cl2, to

which is attached the lifting-rope OX. The

Iswinging yoke or latch D is journaled in the upperpart of the frame O on the shaft c13 and is provided wit-hnotches o! and d' on its upper end to receive the prongs e3 e2 of the trip E. It also is connected with the locking-1e- Vver c7 by means of links cl2, journaled upon both sides thereof and to the locking-lever c7. The trip E is substantially U-shaped and is provided upon its lower end with a buffer c yand has upon its upper end the inwardly-projecting prongs e and e2 and has a verticallysliding engagement with the upper portion of the frame C between projecting lugs C14, cast on the inside of the frame C and on both sides thereof.

For the purpose of locking the carrier to the track While loading and for the additional purpose of tripping the locking mechanism heretofore described I provide a weighted stop-block F, mounted upon the track,-which consists of a frame j', securely bolted to the track, and through one lend thereof and the track there is passed the circular-headed rod f', which has a pivotal connection with the weighted lever f2, pivoted to the rear end of the frame f. To the outer end of the weighted lever f2 there isl attached an operating-rope f3, by means of which the lever may be raised, carrying with it the headed rod f. In operation these stop-blocks may be mounted upon the track at any desired position. The carrier is then placed upon the track and the lifting-rope securely fastened at one end to the clevis or link cl2, journaled upon the lockinglever c?. It is then passed through the pulley G and thence up and through the frame and under the brake-shoe c6. When it is desired to lock the carrier to the track at the point of. loading, one of the locks or stop- IOO blocks F is mounted upon the track at that point. When the carrier passes thereunder, the depending head f4fof the headed rod f thereof engages with the swinging yoke or latch D, entering the opening d2 therein, and causes the same to swing over upon its shaft, carrying with it the links, by means of which the locking'lever c7 is raised, thus elevating the brake-shoe cs and disengaging it from the lifting-rope. At the same time the prongs c' and e2 upon the upper portion of the trip E drop into the notches d and d' in the swinging yoke or latch D, thus locking the swinging yoke or latch D in its upright position and pre-- venting the movement of the carrier upon the track.- The rope is then pulled down until the hay-fork carried upon the pulley Gris engaged with the load, when the load may be lifted to any desired height, and the rope f3 is then operated so as to raise the lever f2, carrying with it the headed rod f', the head of which engages with the prongs e' and c2 upon the upper portion of the trip E, raising the same out of the notches d and d', and the tripthen becomingdisengaged from the swingl ing yoke or latch the same again turns upon its journal, throwing down the links which connect it with theA locking-lever c7, which causes the brake-shoe to thoroughly grip the lifting-rope and to hold the same against movement. In case it is desired to use a triple draft-sling I disengage `the clevis cl2 from the locking-lever c7 and put in place thereof the pulley H. I then providein place of the pulley Gr two pulleys I and J, having hooks upon their lower .ends for engagement with the hay-sling. To the pulley .I there is attached the clevis j, to which the end of the lifting-rope is securely attached after having passed through the pulleys I and J and over the pulley H.

It will be observed that I have provided a device in which all of the operative parts employed in the raising and lowering of the load are contained within and mounted upon the lower swiveling member of the carrier-frame and that when the stop-block is employed it can become operative or inoperative at the will of the operator. A

Having thus fully described my invention, what I desire to secure and claim by Letters Patent is- 1. A carrier having an upper and a lower frame swiveled together, the lower frame carrying a vertically-movable brake-shoe adapted to grip the draft-rope, a swinging latch journaled in the lower frame, and having a linked connection with a locking-lever journaled in said frame, and means for engaging said locking-lever with the lifting-rope, and a linked connection for said locking-lever with the brake-shoe, substantially as described and vset forth.

3. A carrier having an upper and a lower frame swiveled together, the lower part there'- of provided withl a movable brake-shoe, a swinging latch journaled in said frame, means for connecting the same with the brake-shoe, and a vertically-sliding trip adapted to engage the swinging latch, substantially as described and for the purpose set forth.

Il. A carrier having an upper and a lower frame swiveled together, the lower frame carrying a vertically-movable brake-shoe adapt ed to grip the draft-rope, a swinging latch journaled in the lower frame, and having a linked connection with a locking-lever journaled in said frame, a triple pulley mounted thereon, and a linked connection between the brake-shoe and the locking-lever, substantially as described and for the purpose set forth.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.

JOHN H. BURKHLDER.
